Hi! I am pretty new to lego and I started for a few days to make my rcx work under Linux. After I passed all the makefile issues, gcc 3.3 mlsl problems, I still get this error from memcpy.c: make[1]: Entering directory (...) (21 years ago, 3-Sep-03, to lugnet.robotics.rcx.legos)

Natural log (ln), and square root. Also useful would be x^y where x and y have fractional parts. I see you have done it with just x as a float and y as an int. This would incorporate the square root by doing x^1/2 "nanobapt" <nanobapt@wanadoo.fr> (...) (21 years ago, 30-Aug-03, to lugnet.robotics.rcx.legos)

I've posted an enhancement request on the sourceforge website for someone to write a full math.h. I would do it myself but my programming skills aren't very good. Your math.h looks like a good start. Hopefully someone will build on that. Thanks for (...) (21 years ago, 30-Aug-03, to lugnet.robotics.rcx.legos)

I'm having trouble finding a maths header file. It's usually called "math.h". I need to do stuff like sine and cosine, and use the "abs" function to make a number positive. Does a file like this exist? Are there any plans to incorporate a maths (...) (21 years ago, 29-Aug-03, to lugnet.robotics.rcx.legos)

Is it possible to use threads within threads?

I mean, I assume that thread1 (...) (21 years ago, 27-Aug-03, to lugnet.robotics.rcx.legos)

Hi, I'm trying to get brickos working on a linux box running mandrake. I downloaded gcc-2.95.3 and binutils-2.13.1 and compiled them to make a cross compiler. That seems to have worked successfully. Then I ran ./configure;make to make brickos (...) (21 years ago, 19-Aug-03, to lugnet.robotics.rcx.legos)
